PAPERBOX-N|AKING lVlACHlNE.

SPECIFICATION forming part of Letters Patent No. 655,695, dated August 14, 1900.

.Flpplication illed February 5, 190Q. Serial No. 4,093. (No'modelJ ing machines for folding paper boxes or car-' tons.

The primary object of the invention is'to provide a simple efficient machinewhich can be adapted to automatically formboxes of Various sizes from a continuous roll of paper or pieces that may be fed from a hopper in the ordinary way. The material when intermittently'fed from a continuous roll or sheet passes upwardly between horizontally-reciprocating punching-dies that cut from it only such corners or parts that will facilitate the closing of the box when used, thence passing horizontally between intermittently-actuated feed-rolls over a gluing-roll that applies the glue to one edge, thence passing beneath a vertically-vibrating knife that cuts off apredetermined length for a box, which piece falls upon a reciprocating table having secured thereon plates forming scoring-grooves, its

outer end being seized by vibrating holdingnippers secured to an arm of the table which moves onward, carrying the paper as it is firmly held on the table by means of the nip-' pers beneath revolving scoring-wheels having scoring-edges that crease the paper at points where it is to be folded as it is brought beneath the holding pressure-rollers and in contact with stationary an gularly-formed guides, one on each side, that bend or fold the paper over, so that its two outer edges, one of which has been previously glued, are brought in contact and passed beneath the next succeeding rollers, to which it is delivered by the reciprocating table. Said'latter rollers press and firmly secure these edges together as the now flat-folded completed box passes outwardly and is discharged from the machine.

In the accompanying drawings I have shown my improvements as arranged in the most practical way to secure rapid accurate work without liability of disarrangement or injury to any portion of the, material or stock that is being used. Obviously, however, some of the parts may be used without others and the construction somewhat varied without departing from the main features of my invention, as hereinafter more fully described.

In the drawings, Figure 1 represents a side elevation of my improved machine, showing the material as being received from. a continuous roll of paper. Fig. 2 is a plan of the same, showing the main drivepulleys and the several operative parts of the machine; Fig.

3, a longitudinal vertical section of the same. Fig. 4 is a detail View of the reciprocating table and the vibrating holding-nippers, that are also shown separately open in dotted lines. Fig. 5 is a plan view of the same; Fig. 6, the intermittent feed operating-pawl and ratchets and its pitman connection that is actuated by the sliding crank connection in the slotted wheel of the main drive-shaft.

In the drawings, A represents the main frame; B, the main drive-shaft 5 B, the contin- .uously revolving feed-driving wheel that imparts intermittent motion to the feed mech ,anism; B, its grooved crank-actuating slot; Bathe pitman connection, imparting intermit ,tent action to the feed-operating pawls mounted on their carrying-disk that is loosely j our naled at the side of the ratchet-wheel 13 that is secured to the drive-shaft 13 that is pro-" vided with gearing at the other end, imparting motion to corresponding gear-wheels for actuating the feed-rollers and gluing-roll.

G is the horizontally-reciprocating punching-die; 0, its punching-plate; O, the die- .plates; (these plates may be removable and of any form;) 0 its forked actuating-pitman; 0 its eccentric connection with the main drive-shaft.

D is thedouble-armed crank, secured centrally to the main driving-shaft and actuates the pitman-rod D, that is secured to the lug D of the horizontal laterally-reciprocating table D G is the roll of material; G G, paper-guiding rolls; G, a paper-guiding roll at the top of the machine, provided with flanges at each end. It is mounted in a slotted support on the main frame, and is therefore adjustable and can be secured at any desired point to register the paper in relation to the point where it is cut off, which secures the proper position as regards the die-punching mechanism; G the upper holding pressure-roll bearing on the paper that passes over roll G.

His the glue-reservoir; H, the gluing-roll. I, the vertically-vibrating knife-arm, pivoted on the main frame at 1 1, its friction-rolls, that are caused to vibrate the knife downwardly as the projecting knife-actuatin g arms I I, that are secured at each side to the reciprocating table, pass over said rolls; 1, the knife-retractingspring, secured near its pivotal support; 1 the knife-blade.

J is the vibrating-holder nipper-shaft; J, its supporting-arms, secured to the horizontal laterally-reciprocating table; J, the centrally-secured paper-holding nippers; J the actuating-pinions,secured on the nipper-shaft;

J the pinion-actuating rack, thatis movablyi supported in sliding bearings D secured on the reciprocating table. The nipper J is provided at the other end with a ratchet-Wheel J and held by the pawl J which pawl is provided with a friction-roll J A pressure holding-spring J 9 holds the nippers down firmly on the table, and as it is moved outwardly its end will contact with a fixed lug A secured to the main frame. This contact will move the rack J 4 backward in its sliding bearings D and its teeth will revolve the pinion J 3 and its shaft J to open the nippers up and over away from the table, in which position they are held by means of the pawl J 5 and ratchet-wheel J and thus release and open the way for the paper as it is seized by the pressure-roller K As the table passes back the pawl-releasing frictionroller J 8 on the pawl J 5 will come in contact with the disengaging-stop J secured to the main frame, and lift the pawl out of engagement with the ratchet-teeth J secured .to the shaft J, and permit the force of the pressurespring J to returnthe holding-nippers J to the table and renew its functions.

The paper is received by the pressure-rollers K and folding-guides K, by means of which it is folded over and the two outer edges firmly pressed between the pressurerollers K of which I have shown in use four above and four below, between which the outgoing box passes. Motion is imparted to the outside of the lower pressure-rollers K by means of an endless belt that receives its motion from a pulley on the main driving-shaft, and the upper rollers will revolve by frictional contact with the moving paper. Thus the drawings will clearly show a machine which in its operation will carry the paper from a continuous roll to a point where it is acted upon by the punching-dies, thence over a guiding-roll,presenting it to thezforce feedingrolls G and Gflthat force it over the glue-roll H and under the vibrating knife I and when a sufficient length has passed beneath the knife it will be cut off, as the projecting arms I, secured to the reciprocating table, press down upon the friction-rollers I of the vibrating knife-arm I, the severed piece falls upon the surface of the tab1e,an-d its outer edge is seized and held upon the table by the, nippers J", and the table moves outwardly beneath the scoring-rolls S, of which there are four secured to the shaft S and actuated by frictional contact with the paper, the scoring edges being placed to be above the corresponding grooves in the table upon which the paper rests, and as it is scored it passes onward beneath the pressure-rollers K and against the foldingguides K, that cause it to assume a fiat-folded condition. The outer edges being brought in contact, the glue will cause them to adhere as the pressure-rollers K firmly press upon them and discharge them from the machine.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a box-making machine the horizon tally-reciprocating die located at the front of the machine, the guiding-roll G the intermittently-actuated feed-rolls G G, the glueroll H, the vertically-vibrating knife combined with the reciprocating table that moves in a direction parallel with the line of the movement of the outgoing or traversing paper, that is being scored and folded substantially as shown and described.
